Abstract
The utility model provides a circular fire prevention valve, includes valve body and two semicircular blades, fixedly in the middle of the valve body being provided with the fixed plate, but the blade walk around the pivot and extend one section and form the blade closing plate through pivot swivelling joint, blade with the fixed plate, the both sides edge of fixed plate has set firmly the spring leaf, during blade rotation to closed condition, the blade closing plate forms the sealing strip with the spring leaf contact. The utility model discloses utilizing the contact of blade closing plate and spring leaf, having utilized the deformable characteristic of spring leaf to form the sealing strip, the structure is exquisite, and is sealed reliable, the utility model discloses in when applying the wind pressure to the blade, the blade is through the leverage of rotation axis, wind -force is big more, the blade closing plate is big more with the packing force of spring leaf, sealing performance is good more.
Description
Technical field
This utility model is related to fire-fighting equipment field, more particularly to a kind of circular fire resisting damper.
Background technology
Circular fire resisting damper is arranged in passage of central air conditioner system, and operation principle is using the easily fusion installed on valve
The temperature control of gold, using action of gravity and the effect of spring mechanism, when fire occurs, flame invasion air channel, high temperature makes valve
Fusible alloy on door melts, or making memorial alloy produce deformation is automatically switched off valve, runs through with fire compartment for air channel
Occasion.
Only connection, sealing are contacted by blade firmly between existing fireproof valve blade and blade, between blade and valve body
Poor, how to design a kind of fire resisting damper of good seal performance becomes technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of circular fire resisting damper, so as to solve aforementioned present in prior art asking
Topic.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of circular fire resisting damper, including valve body
With two semicircular blades, fixed plate is fixedly installed in the middle of valve body, blade is rotatably connected with fixed plate by rotating shaft, leaf
Piece bypasses rotating shaft and extends one section of formation runner sealing plate, and the both sides of the edge of fixed plate are installed with spring leaf；Blade is rotated to pass
During closed state, runner sealing plate contacts to form band with spring leaf.
Preferably, the thickness of spring leaf is 0.02-0.08mm.
Preferably, the thickness of spring leaf is 0.03-0.06mm.
Preferably, the thickness of spring leaf is 0.05mm.
Preferably, circular fire resisting damper inner port edge is fixedly installed semiorbicular annular seal plate.
The beneficial effects of the utility model are：This utility model is contacted using runner sealing plate and spring leaf, make use of bullet
The deformable characteristic of reed forms band, delicate structure, sealed reliable；When applying blast to blade in this utility model, leaf
The leverage that piece passes through rotary shaft, wind-force is bigger, and runner sealing plate is bigger with the thrust of spring leaf, and sealing property is better.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.It should be appreciated that specific embodiment described herein is only to explain this practicality
It is new, it is not used to limit this utility model.
Embodiment：As depicted in figs. 1 and 2, a kind of circular fire resisting damper, including valve body 1 and two semicircular blades 2, valve
Fixed plate 3 is fixedly installed in the middle of body 1, blade 2 is rotatably connected with fixed plate 3 by rotating shaft 5；As shown in Figures 4 and 5, blade 2
Bypass rotating shaft 5 and extend one section and form runner sealing plate 4, the both sides of the edge of fixed plate 3 are installed with spring leaf 7；Blade 2 rotate to
During closed mode, runner sealing plate 4 contacts to form band with spring leaf 7.
The thickness of spring leaf 7 is 0.02-0.08mm, and the thickness of spring leaf 7 is alternatively 0.03-0.06mm, preferably, bullet
The thickness of reed 7 is 0.05mm.
Circular fire resisting damper inner port edge is fixedly installed semiorbicular annular seal plate 6.
By using above-mentioned technical proposal disclosed in this utility model, having obtained following beneficial effect：This utility model
Contacted using runner sealing plate 4 and spring leaf 7, make use of the deformable characteristic of spring leaf 7 to form band, delicate structure is close
Envelope is reliable；As shown in figure 3, when applying blast to blade 2 in this utility model, the leverage that blade 2 passes through rotating shaft 5, wind-force
Bigger, runner sealing plate 4 is bigger with the thrust of spring leaf 7, and sealing property is better.
What is should illustrated is that fire resisting damper is also used as smoke exhaust fire damper, exhaust smoke valve in fire prevention ventilation installation
Use, according to name is used environments to, but practical structures are identical for these three titles.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching should also regard protection domain of the present utility model.
